MFJ-1278B MULTI-MODE OPERATIONAL COMMANDS
DISPLAY [class] Mode: All Immediate Command
Parameters:
class Optional parameter-class identifier, one of the following:
ASYNC Displays asynchronous port parameters
CHARACTE Displays special characters
ID Displays ID parameters
LINK Displays link parameters
MONITOR Displays monitor parameters
TIMING Displays timing parameters
S Displays a group of parameters such as memory buffer contents, CW
parameters and parameters which affect the printing of graphics to the
printer and to the computer screen.
HEALTH displays 24 counters*
*The twenty four counters in the MFJ-1278B are 16 bits wide, and are ALWAYS initialized
to 0000 on power up or "RESTART". These health counters are not listed in the standard
command listing. Also when telling the MFJ-1278B to display with the DISP command they
will not show there either. However, we have listed them here for your convenience.
ASYFRERR:
This is a health counter reflecting the number of hardware-detected asynchronous framing
errors. Framing errors are not fatal. They merely indicate that the terminal attached to your
MFJ-1278B is not configured correctly with regard to AWLEN/PARITY.
ASYQOVER:
Records the number of times received- connected packets have been rejected due to
insufficient space in the buffer holding the data going to the terminal. No actual data loss
occurs, provided the connection remains intact. ASYQOVER counts can be avoided by
increasing the speed of the attached RS-232 terminal and/or printer. (SEE also SENTRNR)
ASYRXOVR:
Increases when the software does not service the asynchronous receiver in time. Indicates
data from the user to the MFJ-1278B is being dropped. This error counter should never
become non
-
zero under supported data rates.
